The Delta Force (1st Special Forces Operational Detachment-Delta), is a U.S. Army unit used for hostage rescue and counterterrorism, as well as direct action and reconnaissance against high value targets.elta Force was formed after numerous, well-publicized terrorist incidents in the 1970s. These incidents led the U.S. government to develop a full-time counter-terrorism unit. Key military and government figures had already been briefed on a model for this type of unit in the early 1960s.
Force Protection Delta, or FPCON Delta, is a threat level indicator  where a terrorist attack has just occurred, is currently taking  place, or is highly imminent based on râ¦ecent intelligence. The  FPCON levels are similar to the Defense Readiness Condition, or  DECFON, levels. The main difference between these two systems are  that the DEFCON system deals with military readiness against  threats to the public while the FPCON system is specific to threats  against the military.
